Description
Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The VPN gateway must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. NIST cryptographic algorithms approved by NSA to protect NSS. Based on an analysis of the impact of quantum computing, cryptographic algorithms specified by CNSSP-15 and approved for use in products in the CSfC program, the approved algorithms have been changed to more stringent protocols configure with increased bit sizes and other secure characteristics to protect against quantum computing threats. The Commercial National Security Algorithm Suite (CNSA Suite) replaces Suite B.

Who does this work

8 NICE work roles and 7 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.
